研究目的: |
1. 揭示不同流速模式对肥胖患者呼吸力学(肺顺应性、气道压)及氧合功能的影响规律;2. 验证PCV-VG模式下吸气时间与呼吸频率优化对术后肺部并发症的降低效果,为肥胖患者肺功能改善需求提供理论框架。 |

|
Objectives of Study: |
1.To reveal the influence patterns of different flow rate modes on respiratory mechanics (lung compliance, airway pressure) and oxygenation function in obese patients; 2.To verify the effect of optimizing inspiratory time and respiratory rate under the PCV-VG mode on reducing postoperative pulmonary complications, and provide a theoretical framework for meeting the needs of improving lung function in obese patients. |
